DEVICE FOR HOLDING PLOWSHARES.

Specification of Letters Patent.

Patented Jan. 14:, 1908.

Application filed May 11,1907. Serial No. 373043.

To all whom it may concern:

Be it known that I, PAUL V. BURGESS, a citizen of the United States, residing at Greenwood, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Devices for Holding Plowshares, of which the following is a specification.

My invention relates to improvements in devices for holding plowshares during the process of sharpening and drawing; and my objects are first, to provide a rigid but simple device which may be manufactured at small cost; second, to provide a powerful device which will firmly grip one entire side of the plowshare and prevent it from warping during the rocess of sharpening and drawing, and third to provide a device which a blacksmith may reliably hold in a steady manner while the process of sharpening and drawing is performed with the modern trip or ower hammer.

eretofore it has been practically im ossible to sharpen and draw a plowshare wit 1 the modern trip or power hammer because the heavy, rapid blows struck by said hammer make it difficult to hold the tool sutliciently steady while sharpening and drawing the plowshare. I overcome this dilliculty by providing my device with an extension handle, which may be firmly gripped with both hands, and a body-brace at the rear end of,

the handle which may be placed against the body of the blacksmith and thus assist the hands in holding the device steady, so that the plowshare may be held from vibrating or moving around unsteadily under the blows of the hammer.

In order that the invention may be fully understood reference will now be made to the accompanying drawing, in which Figure 1 represents a perspective view of the device, with a plowshare in position thereon. Fig. 2 is a plan view of the device.

In carrying out the invention I employ a V-shaped handle 1, made preferably of a single piece of strap iron. Said handle is provided at its forward ends with a clampingmember for reliably clamping the plowshare 2. Said clamping-member consists of a transverse bar 3, a series of clamping-heads 4 spaced equal distances apart, and clampingscrews 5, adjustably mounted in said heads and adapted to engage and firmly hold the plowshare 2 in engagement with the trans- Verse bar 3 so that said plowshare may not warp during the process of sharpening and drawing.

Bar 3 is made heaviest at its central under portion, so that it will not bend beneath the strain imposed thereon when the central clamping-screw is adjusted firmly into contact with the plowshare. The terminals of bar 3 are secured to the undersides of the terminals of the handle which are reinforced by a pair of braces 7 secured to the undersides of bar 3 by a pair of rivets 8, which also pass through the ends of the handle and thus reliably bind said handle, the bar, and the braces together. The handle is further reinforced by a transverse brace 9 secured thereto by rivets 10.

11 designates a body-brace provided at its forward side with a lip 12 extending over the rear end of the handle and detachably secured thereto by bolts 13, so that said bodybrace may be removed when desired.

In practice one side of the plowshare is placed upon bar 3 and reliably secured bythe clampingscrews 5 which are spaced apart so that they will grip the plowshare near its ends and at a point intermediate thereof, so that it cannot warp during the sharpening and drawing process, as would be the case if it were gripped only at its central portion. The sides of the handle are then grasped with both hands, and brace 11 is placed against the body so that the plowshare can be held trip-hammer.

By providing the device with an extension handle, one side thereof may be placed against the body while the other side is firmly grasped with the hands so that the smith may get nearer to the work for a closer ishing touches.

Having thus described my invention, what I claim and desire to secure by Letters-Patent is 1. In a device of the character described, an extension handle, a clamping member consisting of a transverse bar connecting the forward ends of said handle, individual clamping-heads spaced apart upon said bar, and clamping-screws adjustably mounted in said heads, and braces secured to the transverse bar and the sides of the handle for reinforcing the same, substantially as described.

2. In a device of the character described, a V-shaped handle, a clamping member comprising a transverse bar secured to the under in a steady manner while being struck with a inspection thereof while putting on the tin-- side of the forward ends of the handle, clamp- In testimony whereof I affix my signature,
